Problems with Grail 0.6 and Python 1.5.2 (NT)

[Chris...]

Hello

  I've just downloaded the latest version of Grail, but got the following
error:

My system is Windows NT 4 (SP5), Python 1.5.2 and TCL8 (that from the Python
distribution, btw. the installation program doesn't add a path to tcl
automatically, that was my first problem...).

  What's going wrong here (Grail 0.5 did work alright).

  Thanks a lot in advance!

bye
